Do you have any more information about your Joseph Wild? Family, approximate year of immigration, place of birth? Wild is a somewhat common name in the Bas-Rhin department. It was originally spelled Wilt or Wildt in German.
I did a quick search of a French genealogy website and found a Joseph Wild in a couple family trees who was born 5 January 1857 in Strasbourg, married Eve Siegel (1861-?) on 2 September 1884 in Kuttolsheim, and is the son of Francois Antoine Wild and Madeleine Mattis. Does that match your Joseph Wild?
